'MAGAZINE PENCIL.

mentation mea August e', 192s. semi No. 655,288.

The present -invention relates toa pencil construction of the type in which leads may be contained within the pencil in a magazine within the pencil, and individual leadsmaintained at thepoint of the pencil in a predex termined position and fed outwardly as the individual .lead is used and worn down.

The object of the invention is to provide a pencil of the type mentioned, which is simple in construction and composed' of` few parts which may be economically manufactured at low cost.

Reference should be had to the accompanying drawings forming a part of this specification, in which. Fig. 1 isa sectional elevation of the pencihFig. 2 is an elevation with portions in section showing .parts of the pencil in disassociated relation; Fig. 3 is a top plan view of a retaining member; Fig.' 4 is an elevation of a portion of the pencil; lFig. 5 is an elevation'of another portion of the pencil. f f

Referring to the drawings, 1 indicates the barrel of the pencil which at its upper end is lopen ended and at its lower end is provided withv a portion of lessldiamete'r, as indicated at 2, and providing a shoulder 3. The lower end of the part, has inwardly 'slanting sides, as indicated at 4, and there is a reentrant slot 5 at the end of the tapered portion 4.

(io-operating with the lower portion of the barrel 1 isa conically shaped head 6, which. head' at its upper end is provided with-- straight cylindrical wall portion indicated spect to barrel 1 uponthe lower end therethe reentrant slot 5 of, as indicated in Fig. 1, the cylindrical portion 7 abuts against the shoulder 3, and the angle of the tapered portionv 4 corres onds with the taper on the inside wall of t e member 6.

Within the member 6 there is an annular ridge 8 which may be formed directly in the metal itself, as is indicated in thedrawing, or any other means may be utilized to provide the equivalent of this ridge 8.

Upon theinner wall of the member 6 and justvabove the ridgev 8 there is a short member 9 which is either aiiixed to the innerwall 'of the member 6 or formed as a part thereof, this member 9 being adapted to extend into when the member 6 is assembled with respect to the barrel 1, thereby preventing relativerotation vbetween the portions 13 and 13a,

-der 15.

which is of reduced diameter,`

4ed opening means for guiding head 6 and the barre l 1,ibut' permitting llon` i gitudinal or axial movement.

Within -the member 6 there 1s apart gen-' I. .i erally indicated at '10,' which is provided with.

an axial opening indicated at 11 in Fig.y l.

The upper end of this member isth'readed,`

as indicated at 12, and the portion-'which lies 5 n below the threaded part just indicated is i split solasto form two partsll andlfa. "At

the lower end of the member 12 there is. a

conically shaped head 14 which'attsbase is diameter than the split thereby forming'a shou1. The angle of taper ofthe portion 14 corresponds with the angle of the" inside wall of the member 6.

'The splitting. of the of slightly greater parts 13 and 13a 1s carrled'through the coni# F5 be correctly de'scribedasAA cal portion 14, andthe twofparts ofthe 'coni-` cal member 14 may grippingjaws. The inherent resiliency of the metal, particularly the metal contained Vin the parts 13 and 13a, will normallyl hold thefgripping jaws apart, and when the conical portion or the ipping j aw .portions are moved toward eac other, and subsequently i member into the I released?, the resilience of the metal will move I the gripping jaws apart.

Vithin the barrel member 1, at thelower portion thereof and (3o-operating with thel slanting wall portion 4,5is a member 17 hav'- ing a portionof its outside wall made slant'- as indlcated at 16, and at the upper poring tiori of this 'member the outside surface is cylindrical, as -indicated at 17a. This mem' the barrel v1 has ber when assembled within its lower tapered portion 16 cooperating. with the tapered portion 4, and its cylindri. cal portion co-operating with thecylindrical portion of the barrel member 1 which 4is just. above the tapered portion 4.

This member 17 has a snug lit within-the barrel .member so that when the two are fas'- sembled they are held together by the friction engendered by the engagement o adjacent walls. i f

The member 17 is'providedwith l which is adapted to receive threaded end "12 of the member 10,- and this' opening at its upper lend is made flaring, as indicated, at 18,- so as'to provide an eicient leads which may-be contained within the barrel 1 into the channel.

11 of the member 10.- i

' When theparts which have been described ioo fthe i 'a thread-4 f the,V j f l in this member 19.

' ly, and inasmuch as the member 19 is press-.

cal head portion 6 with the conical portion 111 of the member 10 in engagement with the inner walls of the' member adjacent the end thereof. v

vThe head member 6Vat its lower' end is provided with a straight 'opening 6,a which is in line with the opening through the member 10, as clearly shownin Fig. l.

.There is a retaining member 19 which is more clearly vindicated in Fig. 3,'which is preferably made of sheet metal, and preferably slightly dished, the metal having suficientresiliency so that in assembling the member 1 9 within the head member 6 this member" 19 may be snapped past theridge 8 withits peripheral edge in engagement with the lower portion ofthe ridge. The natural expansive tendency of the member 1 9, taking v linto consideration the fact that theportion of the member 6 below it is of reduced diameter, causes the edge'of this member 19 to wedge tightly and firmly against the under side of the ridge-8. i

The member l19 'is provided with a central opening 19a @which is of slightly greater diameter than the member 10, so that the member 1.0may freely pass through the opening Thel particular form of the member 19 which is shown in Fig'. 3 is not essential, but this form does give the required resiliency' of the metal, which is necessary in order to snap it beyond the ridge 8 in assembling the parts of the pencil. A

Below the member 19 there is a spring 20, which spring at one end bears against the under side of the member 19 and at its opposite end' bears against the shoulder 15 of thel member l0, so that the fun'ctionof the spring 20 is to urge the member 19'upw`arding against the ridge 8 which forms a part of the head`6, the spring 20 may be saidV t-o .con-

tinuously urge the head member 6 ofthe pencil into lposition with respect to the barrel'1 in which it is shown in Fig. l,.that is to say, with the end of the head member 6- in engagement with the shoulder 3 at'thelower portion of the' barrel 1.

When thefheadmember 6 is urged to its uppermost position, as has just been Vdescribed, the conicalportions 14 of the member 10, which in 'effect form gripping jaws,

.are urgedtoward each other, and so will firmly grip a lead which' may be in position inthe channel 11 which is formed in the member 10. v a

When itis desiredto feed the lead further forward, or topush-the lead back, so that the point is wholly within the head member 6 of' the pencil, the member 6 mayl be gripped by the fingers and4 pulled a slightl a immerse j distance away from the barrell -1,` which wouldserve' to release the pressure on the members 14 and sorelease the grip on vthe lead which is within the channel 11, so that theleads may move outwardly under the action of gravity, or it may be pushed up so as to protect the point of the lead.

At the oppositev end of the barrel member 1 there is ,an inserted member 21. This member has a cylindrical portion 22 which is adapted to snugly engage with the inside wall of the` barrel lat the outer end of the barrel. This engagement, however, is not so tight that it can not be removed, but is suficiently tight so that'the member 21 is re-l tained when it is inserted in thevend of the barrel 1; Above. the portion 22 which has been described there is a part of slightly greater diam-eter, as indicated at 23, thereby This member 21 is hollow and receives an eraser member 25, which may be made of rubber or such erasive material as may be desired lThere is also a cap 26 .which is formed with a cylindrical body portion yadjacent one end thereof, which is adapted to engage `with the outside surface ofthe portion 23 of the member 21, this engagement being a frictional enfgagement in which there is a snug t in en-l gagement so as to prevent accidental displacement of the parts, but not suiiiciently. great to prevent their being separated when vsuch is desired.

The cap may be provided with a beaded part 27 which fits over the end of the barrel member 1, obviating any sharp edges and giving a finished appearance.

The portion of the cap above the cylindricaI part 26 may be given any desired form, the only requirement being that there should be sufficient room to receive thev end of the eraser member 25.

At, the upper end of the cap member 26 there vmay be provided an arrangement whereby a llead may be pointed, and in the present instance the construction provides-a plate 28 which is secured to the cap 26 by providing an annular recess 29 in the wall of the cap and crim ing the metal in the edge of the cap aroun the edge of the member 28. The member 28 is provided with a -conical recess 80 which may be formed to jwithout removing the lead, but rather re- -moving the cap and inserting the end of the lead into` the conical sharpening member 30.

. containing leads,

- ber 17.' The ends The space within the barrel member l mayrconveniently serve as a reservoir for and these leads may be inserted by'removing the cap 26 and the memherxQl.. l

Leads which are contained within the barrel :member l willbe automatically fed into ,the channel ll-jon the member because the pencil, which is usually carried inv vertical position, will cause the leads to move-toward the lower end of the barrel portion and be in contact withthe u perl part of the memv Thechannel is vof such size that it cannot .receive more than one lead, so that there will be -nogjamming n wia, or course, be Obvious um.- lir a he desired a lead maybe inserted throu `h the o ening 6B' in the head member 6 of t e penci by moving the head member 6. against the attio'n, of spring l2 soas to; open the jaws 14.-"
